Sequences showing the real images acquired with the VLT, and 2D and 3D animations illustrating the motion of the stars around the black hole at the centre of the Galaxy.

00:10 - zoom and pan the colour image obtained with the VLT; 00:56- zoom in real images of the galaxies, starting from a wide angle view, all the way to the sequence of real images showing the stars orbiting the black hole at the centre; 01:30- fade from the real data to a 3D animation of the stars around the black hole; 02:00- 3D animation showing the S2 star orbiting the black hole 02:35- 2D animation with all the measured stars, reproducing the real observations.
